Shape: Circular Color: Blue Appearance: Transparent

The provided material contains only an image without detailed textual product data. Based on visual analysis, the product is a Blue Optical Window. The image shows two circular optical windows in different sizes, featuring a uniform blue transparent body with finely polished edges and a smooth, clear surface. These windows are designed to transmit light while isolating or protecting internal optical systems from dust, moisture, and mechanical damage. They are commonly used as protective or viewing elements in optical instruments, sensors, and laser equipment. Specific technical data such as material, dimensions, and coating details are not provided in the source material.

Substrate Material: BK7 / Fused Silica Coating Type: Protected Aluminum (Al+SiO₂) Diameter: Ø12.7mm / Ø25.4mm / Ø50.8mm

The product shown in the image is a set of round, flat optical mirrors with a metallic (silvery-gray) reflective surface and a precision-polished edge. Based on the visual characteristics, these are broadband protected aluminum mirrors, consisting of an optical-grade substrate (typically BK7 or fused silica) coated with an aluminum reflective layer and a protective dielectric overcoat (e.g., SiO2). The protective coating prevents oxidation and scratches while maintaining high average reflectance across the visible and near-infrared spectrum. These mirrors are available in multiple standard diameters and thicknesses, making them suitable for general beam steering, folding, and reflection tasks in laser systems, imaging devices, and optical instruments where broadband, cost-effective reflection is required.
